Abstract

The invention discloses a stratosphere atmospheric pressure increasing and decreasing device, and the device comprises a constant pressure chamber (1), a pressure control component (2), a pressure monitoring component (3), an gas storage chamber (4) and a central control unit (5); the constant pressure chamber (1) is used for setting an atmospheric in-situ photochemical component detection instrument; the pressure control component (2) is used for controlling gas to enter the gas storage chamber (4) and the constant pressure chamber (1), so that the pressure of the constant pressure chamber (1) is kept within the range of 800-1100 mbar; the pressure monitoring part (3) is used for monitoring the pressure of the constant pressure chamber (1) and the pressure of the gas storage chamber (4) and sending pressure data to the central control unit (5); the gas storage chamber (4) is used for storing the atmospheric pressure gas compressed by the pressure control part (2) from the outside andinjecting the gas into the constant pressure chamber (1); and the central control unit (5) is used for receiving the pressure data and outputting a control signal to the pressure control component (2)according to the pressure data.

Description

technical field

[0001] The invention belongs to the technical field of space environment detection, and in particular relates to a stratospheric pressure increasing and decreasing device and method. Background technique

[0002] Near space is an airspace that has not yet been systematically developed and utilized. Due to its important strategic significance and application value in military, scientific exploration, and in industries such as communications, navigation, agriculture, meteorology, manned tourism, and geographic surveying and mapping, the United States, Russia, The European Union, China, Japan, Israel and other countries have deployed relevant project plans. Using 10-40 km balloons or airships to carry out near-space stratospheric environment detection is an emerging and popular detection field. Photochemical components such as ozone and nitrogen oxides in the stratosphere have a significant impact on the global climate, but there are few in-situ detection data ...
